Direct-response ultraviolet thermoluminescent dosimeter.

An integrating solid-state dosimeter has been developed to detect ultraviolet radiation using the process of "direct" ultraviolet stimulation. This process yields a thermoluminescent signal after an exposure to ultraviolet radiation, without prior exposure to ionizing radiation. Magnesium oxide crystals were found to show a directly stimulated thermoluminescent glow peak at 145 degrees C which can be utilized as a linear, energy-independent ultraviolet dosimeter.
